New features


PCI passthrough support in OpenStack

Added support for the Peripheral Component Interconnect (PCI) passthrough feature in OpenStack to use, mainly, as a part of the SR-IOV network traffic acceleration technique. Now, MOS enables the user to configure Nova on a per-node basis to allow PCI devices to be passed through from hosts to virtual machines.


OpenStack Victoria support

TechPreview

Implemented support for OpenStack Victoria with Neutron OVS and Tungsten Fabric 5.1.


SR-IOV for OpenStack

TechPreview

Implemented support for the SR-IOV with the Neutron OVS back end topology.


Hyper-converged OpenStack compute nodes

TechPreview

Implemented the capability to colocate components on the same host, for example, Ceph OSD and OpenStack compute.


Tungsten Fabric monitoring

Enhanced StackLight to monitor Tungsten Fabric and its components, including Casandra, Kafka, Redis, and ZooKeeper. Implemented the Tungsten Fabric alerts and Grafana dashboards. The feature is disabled by default. You can enable it manually during or after the Tungsten Fabric deployment.


Alert inhibition rules

Implemented alert inhibition rules to provide a clearer view on the cloud status and simplify troubleshooting. Using alert inhibition rules, Alertmanager decreases alert noise by suppressing dependent alerts notifications. The feature is enabled by default. For details, see MOS Operations Guide: Alert dependencies.


Integration between Grafana and Kibana

Implemented integration between Grafana and Kibana by adding a View logs in Kibana link to most Grafana dashboards, which allows you to immediately view contextually relevant logs through the Kibana web UI.


Ceph RGW TLS

Added the capability to configure the Transport Layer Security (TLS) protocol for a Ceph RGW public endpoint using MOS TLS if enabled, or using a custom ingress specified in the KaaSCephCluster custom resource.
